Description

[0001] The invention relates to a brush bottle for storing and applying a liquid, in particular hoof oil, according to the preamble of claim 1. The invention further relates to an adapter for a brush bottle according to the preamble of claim 14.

[0002] A horse's hoof is of central importance to the animal's health. It must bear the horse's weight and cushion the impact of every step and jump, particularly to prevent damage to the joints. Regular application of hoof oil to the cleaned hoof as part of routine care creates a protective layer. This layer prevents moisture from penetrating the hoof and effectively protects it from infections and fungal growth.

[0003] Hoof oil is traditionally sold in brush-type containers. These consist of a reservoir for the hoof oil, onto which a cap is typically screwed. A brush is usually attached to the cap, which, especially when the container is closed, extends into the reservoir and, depending on the fill level, preferably dips into the hoof oil. To apply the hoof oil to the horse's hoof, the cap must first be unscrewed from the reservoir. The horse's hoof is grasped with one hand. With the other hand, the cap with the attached brush is held, and the oil is applied to the hoof.

[0004] When the brush runs out of oil, it must be dipped back into the reservoir. Unscrewing the cap, handling the cap (with the brush attached) during application, and the potentially necessary repeated dipping are cumbersome steps. Furthermore, this work must be carried out in close proximity to the horse, while simultaneously holding and monitoring its hoof. This creates a risk of the animal stepping on the brush.

[0005] The storage container also needs to be held with a second hand, as it can easily tip over. This poses a particular risk of spilling hoof oil.

[0006] It is therefore an object of the present invention to eliminate the described disadvantages. In particular, a brush-type bottle is to be provided that enables the application of liquid and is particularly suitable for the described application in the care of hoofed animals, especially horses. Above all, the application of hoof oil should be simplified compared to previously known brush-type bottles. In addition, an adapter for such a brush-type bottle is to be provided that fulfills the aforementioned purposes accordingly. Furthermore, a suitable method for applying liquid, especially hoof oil, in the context of animal care is to be provided.

[0007] The aforementioned problem is initially solved by a brush bottle according to the features of claim 1. This brush bottle is for storing and applying a liquid, in particular hoof oil, wherein the brush bottle comprises a reservoir for receiving a liquid, a brush for applying the liquid to an object, and an adapter connectable to the reservoir to which the brush can be attached. According to the invention, the brush bottle is characterized in that a passage is formed in the adapter, which allows the brush to be supplied with liquid from the reservoir.

[0008] Against the background of the underlying problem, it was first recognized that previously known brush bottles are difficult to handle in the described application area. To improve handling, an advantageous solution was found according to the invention, whereby a passage is formed in the adapter to which the brush can be attached. This passage allows the brush to be supplied with liquid from the reservoir. This ensures in a simple way that the brush can be supplied with liquid even when the adapter is attached. In this context, this refers in particular to the state in which the adapter is connected to the reservoir and, in particular, seals it. In an assembled state, the brush is attached to the adapter and the adapter is connected to the reservoir.In this case, the brush, adapter, and reservoir form a single, integrated unit that can be easily grasped and operated by one person, particularly with one hand ("one-handed"). By grasping the reservoir and / or the adapter, the brush attached to the adapter can also be handled. This allows for the one-handed application of liquid, especially hoof oil, to the horse's hoof. The reservoir and / or adapter also serves as the brush handle. Since the adapter has a passage that allows the brush to be supplied with liquid from the reservoir, the brush can be supplied with liquid even while applying the product to the horse's hoof, provided the brush bottle is handled correctly.The liquid, in this case the hoof oil, flows from the reservoir through the adapter to the brush to supply it. This advantageously eliminates the conventionally required, tedious, repeated lowering and dipping of the brush into the reservoir to collect liquid, as well as the need to hold the reservoir with a separate hand. In general, the brush bottle can therefore be used for storing, dispensing, applying, distributing, and / or dosing various liquids.

[0009] The design of the passage in the adapter can be implemented in various ways. Advantageously, the passage is designed so that the liquid in the reservoir supplies the brush with liquid when the brush bottle is tilted in a position suitable for application to the horse's hoof. Alternatively or additionally, the reservoir can be made of a flexible material, so that, particularly by squeezing the reservoir, the liquid can be forced through the passage due to the resulting reduction in volume inside.

[0010] The adapter for the brush bottle according to the invention preferably performs several functions. When connected, the adapter seals the reservoir and, in particular, ensures that the liquid is stored securely. This effectively prevents unintentional leakage and / or contamination of the liquid. In addition, the adapter preferably holds the brush. This gives the brush a defined orientation relative to the adapter (and thus also relative to the reservoir). This allows for handling that is particularly advantageous for the application of hoof oil to the horse's hoof, since the reservoir and / or the adapter essentially serve as a handle for the brush, preferably an extended one, making it easier to grip.

[0011] Unwanted leakage of liquid can be prevented, in particular, by a small cross-section of the passage through the adapter or brush. In this way, the liquid, preferably depending on its viscosity, can only pass through the passage in small quantities. A valve, such as a check valve, can preferably be provided for this purpose.

[0012] The brush can be attached to the adapter in various ways. Thanks to a convenient design of the brush bottle, the brush can be screwed onto the adapter via a threaded connection. This creates a simple and secure detachable connection between the brush and adapter, allowing the brush to be easily replaced – for example, when worn.

[0013] Various designs are conceivable for the brush. A preferred embodiment provides that the brush has a so-called ferrule and preferably a multitude of bristles held by it. The ferrule advantageously has a sleeve-like basic shape which clamps the bristles, particularly at the ends, and thus holds them firmly, preferably permanently.

[0014] Advantageously, a passage is formed in the brush, particularly in the ferrule, extending from an adapter-side end of the brush to the bristles, allowing the bristles to be supplied with liquid. The passage can be designed in various ways. According to a preferred embodiment, the passage runs centrally through the ferrule as a channel, allowing the bristles to be supplied with liquid at their ends held in the ferrule. Preferably, several passages or channels can be provided. These can have the same and / or different diameters. They can be arranged centrally or at different intervals. In this way, each bristle can be supplied with liquid.

[0015] An advantageous design of the threaded connection between the brush and the adapter provides that the brush ferrule has a thread, preferably an internal thread. The ferrule can thus preferably be screwed onto the adapter. In particular, it can be screwed onto a connecting pin with an external thread formed on the adapter. This screw connection creates a non-destructively detachable connection. This connection can preferably provide sufficient tightness to prevent unintentional leakage of liquid. Furthermore, it can preferably be sufficiently mechanically robust to securely hold the brush against the adapter. In this context, an advantageous embodiment of the brush bottle provides that, when fastened, the brush ferrule, with an end face facing the adapter, contacts a contact surface of the adapter.This measure advantageously provides a robust support for the brush against the adapter. Furthermore, the contact point can achieve an additional sealing effect.

[0016] In general, it is advantageous to incorporate features on the brush bottle that effectively prevent unwanted backflow of liquid outside the bottle, particularly onto the outside of the brush, especially onto an outer surface of the ferrule, the adapter, and / or the reservoir. This ensures that the brush bottle can always be used without contamination (avoiding oily hands). It also prevents liquid waste. One such feature is a collection area or element on the brush ferrule. Specifically, this can be achieved by forming a collar, preferably funnel-shaped, to collect liquid flowing back from the bristles. The collar can advantageously be positioned on an upper edge of the ferrule.It can be designed, in particular, so that any backflowing liquid flows directly back into the bristles or the ferrule of the brush and / or at least back into the passage formed in the brush, or is directed there. Preferably, the ferrule and / or an intermediate element provided or inserted between the ferrule and the brush, preferably a sleeve, has a chamfer, particularly for catching backflowing liquid from the bristles. The intermediate element can be annular and / or tubular. The intermediate element can particularly be a sleeve. The intermediate element preferably serves to hold the bristles together in the ferrule, and more preferably to ensure a distance between the ferrule, in particular the wall of the ferrule, and the bristles. The intermediate element is preferably made of plastic.The intermediate element and / or the wall of the ferrule may have a chamfer, preferably a chamfer oriented towards the center of the brush. This serves in particular to collect liquid flowing back from the bristles, preferably to direct it back into the bottle. This also preferably solves the problem according to the invention.

[0017] The adapter for the brush bottle is advantageously screwed onto the reservoir via a threaded connection. As with the connection between the brush and the adapter, a screw connection between the adapter and the reservoir offers the advantage of a secure, leak-proof, and, if necessary, non-destructively detachable connection. This ensures, in particular, the safe storage of the liquid and / or a leak-proof connection between the adapter and the reservoir. At the same time, it provides a simple way to refill the reservoir with liquid after it has been used up.

[0018] As previously described, threaded connections are advantageously provided between the brush and adapter and / or between the adapter and reservoir. It is particularly advantageous for the threaded connection between the adapter and reservoir, and preferably also between the brush and adapter, to be hollow. This allows them to be part of the passage through the adapter, enabling liquid to flow through them.

[0019] The reservoir of the brush bottle can be designed in different ways. According to a preferred embodiment, the reservoir is bottle-shaped with an opening in the neck area, and the adapter can preferably be connected to the reservoir in the neck area. Advantageously, the reservoir has a base area suitable for placing the entire brush bottle upright on it, in particular for setting it down.

[0020] According to a particularly preferred embodiment of the brush bottle, the adapter is angled. Specifically, in an assembled state, the adapter is inclined relative to the reservoir by a certain angle. This angle—preferably with a suitable angle—facilitates handling, particularly when the brush bottle is used on a horse. It allows for easy application of the liquid. A slightly inclined brush relative to the reservoir facilitates access to the horse's hoof. At the same time, it enables easy dispensing of the liquid. The adapter can also be straight. In particular, it can be designed so that, in an assembled state, the brush and the reservoir are aligned in a straight line.A longitudinal center axis of the bottle preferably also runs centrally through the adapter and / or, in particular, the brush.

[0021] The brush bottle can be gripped in different ways. In a simple design, the brush bottle can be gripped directly at the reservoir or at the adapter. A further development of the brush bottle provides that a handle is formed on the adapter, particularly on the back (specifically, in relation to the advantageously provided bend), which allows the assembled brush bottle to be held and handled, preferably with one hand. Such a handle could also serve to hang the brush bottle when not in use.

[0022] It should be noted that the brush-top bottle is suitable for storing various liquids. It is particularly well-suited for oil, specifically hoof oil, which has excellent penetrating properties. Other liquids can also be used with it. For example, it can be used to apply and distribute liquid food products such as oils, vinegars, marinades, spices, and similar items. It can also be used with various types of technical fluids, such as paints, lubricants, sealants, and the like. Many applications can also be found in the medical and pharmaceutical fields for both humans and animals, for example, for applying liquids, tinctures, disinfectants, or for rinsing wounds and similar conditions.

[0023] Preferably, at least one seal can be provided on the brush bottle. In particular, to improve the seal, at least one seal can be arranged between the adapter and the threaded connection and / or between the brush and the adapter. Preferably, a sealing washer, preferably with a central opening, an O-ring, or a similar material can be used as the seal.

[0024] In particular, at least one closure and / or cover element is provided. Preferably, a closure and / or cover element can be provided for the brush and / or the brush bottle and / or its opening. The closure and / or cover element serves, in particular, to securely seal against leakage of liquid and / or to protect the contents from contamination. It can be a mechanically operated closure and / or cover element, for example, a lid that is particularly hinged and / or snap-on. Preferably, a lid can be provided that can be snapped onto the brush. Such a lid can, in particular, completely cover and protect the brush, especially without bending its bristles.

[0025] The aforementioned problem is further solved by an adapter according to the features of claim 13. This adapter is for a brush bottle, in particular for a brush bottle of the type described above, which can be connected to a reservoir, and a brush can be attached to the adapter. According to the invention, the adapter is characterized in that it has a passage that allows the brush to be supplied with liquid from the reservoir. For the advantageous effects and possible configurations that can be achieved thereby, reference is made – insofar as applicable and to avoid repetition – to the preceding descriptions concerning the brush bottle according to the invention.

[0026] Additionally, it should be noted that the adapter can advantageously be designed with a collection area in the region of the threaded connection. This area collects liquid, particularly any liquid running back from the brush, and allows it to flow back into the reservoir, preferably via the passage. This is therefore a supplementary or alternative measure to prevent or at least reduce unwanted backflow of liquid outside the brush bottle, particularly on the outside of the adapter and / or the reservoir.

[0027] The application of liquid, in particular for the application of hoof oil, preferably as part of animal care, can be carried out in particular by means of one or more, preferably all of the following steps: Providing a brush bottle, in particular as described above, filled with a liquid, in particular hoof oil, Lifting an animal's hoof to allow access for applying the liquid, Soaking the brush by either tilting the brush bottle and / or by squeezing the reservoir, Applying the liquid to the hoof, wherein the steps of soaking the brush and applying the liquid are carried out simultaneously, preferably with one hand, by grasping and handling the brush bottle.

[0028] The described procedure offers the particular advantage that the application of the liquid and the subsequent refilling of the brush with liquid required for oiling the hoof can be carried out simply by grasping and handling the brush bottle. This can be done with one hand, allowing the same person to use their other hand to hold the horse's hoof.

[0029] Ideally, various oils and other liquid care products can be applied using a brush-on bottle. It doesn't necessarily have to be special hoof oil. Other oils and care products, such as household oils or other substances, can also be used to treat a horse's hooves. Liquids from many other areas can also be used, such as food, technical, medical, or pharmaceutical fluids, and so on.

[0030] The invention is explained in more detail below with reference to a preferred embodiment shown in the accompanying drawing. This also reveals further advantageous design possibilities of the invention. The drawing shows: Fig. 1 a brush bottle according to an embodiment of the invention in a simplified overall view from the side, Fig. 2 a brush from the brush bottle in simplified perspective representation, and Fig. 3. An adapter for the brush bottle in a simplified perspective view.

[0031] The accompanying drawing serves to illustrate a brush bottle according to a preferred embodiment of the present invention.

[0032] While Fig. 1 shows the brush bottle in its assembled state, referring to Fig. 2 and Fig. 3 on individual illustrations of a brush used on the brush bottle ( Fig. 2) or an adapter used on the brush bottle ( Fig. 3) Since the in the Fig. 2 and Fig. 3 components shown at the in Fig. The brush bottle shown in section 1 is used, and its identical parts are marked with the same reference symbols. The following explanations apply equally to all of the Fig. 1, Fig. 2 to Fig. 3 to be applied and apply equally to these.

[0033] Fig. Figure 1 shows a brush bottle 1 according to an embodiment of the invention in an assembled state. The brush bottle 1 is suitable for storing and applying liquid, in particular hoof oil. Its preferred application is in the care of hoofed animals, especially horses.

[0034] The brush bottle 1 comprises, in particular, three essential components: a reservoir 2, an adapter 3, and a brush 4. The reservoir 2 has a bottle-like basic shape. It serves to hold a liquid 17, which is preferably oil, in particular hoof oil, with penetrating properties.

[0035] An unspecified base area of ​​the storage container 2 is preferably shaped such that the storage container 2 can be placed on it in a way that prevents it from tipping over. An adapter 3 is connected to the storage container 2 via a threaded connection 9 in a neck area of ​​the storage container 2. The adapter 3 and the storage container 2 are screwed together accordingly.

[0036] For improved sealing, a seal (not shown here) can be provided. A seal can be placed or arranged, in particular, between adapter 3 and the edge of the threaded connection 9 and / or between adapter 3 and brush 4. For example, a suitable sealing washer or an O-ring can be used for this purpose. The seal should preferably have a central opening to allow the liquid to pass through.

[0037] As in Fig. Figure 3, which shows in particular the adapter 3 in a perspective view, indicates that the adapter 3 is a connecting element, especially a bent, tube-like element, that can be built between the reservoir 2 and the brush 4. In the assembled state of the brush bottle 1 (see Figure 3), the adapter 3 is a connecting element that is particularly cranked and tube-like. Fig. 1) The adapter 3 preferably ensures that the brush 4 is inclined relative to the reservoir 2 by a bending angle 8.

[0038] At one end facing the storage container 2, the adapter 3 has an internal thread 9a (in Fig. 3 (indicated by arrow 9a). The adapter 3 can be screwed to the reservoir 2 by means of this internal thread 9a, for which purpose the reservoir 2 has a corresponding complementary external thread (in Fig. 1 not visible, as it is covered by adapter 3).

[0039] How to continue Fig. Adapter 3, which is removable from the brush 4, has a connection area opposite it, inclined by the offset angle 8. Brush 4 and adapter 3 are preferably screwed together in this area via a threaded connection, which will be described below. For this purpose, a connecting pin 10 with an external thread is formed on the adapter 3. An annular contact surface 15 extends circumferentially around the connecting pin 10.

[0040] Fig. Figure 2 shows a simplified, detailed view of the brush 4. This brush has a sleeve-shaped ferrule 6 and a multitude of bristles 5 held within it. At its end facing the adapter 3, the ferrule 6 has an internal thread 11 and an annular end face 14 facing the adapter.

[0041] The clamp 6 can have different wall thicknesses. An additional ring-shaped and / or sleeve-shaped intermediate element can also be provided and / or formed between the brush 4 and the clamp 6. In particular, this can be a sleeve made of plastic. The wall of the clamp 4 and / or the intermediate element or the sleeve can be chamfered on its upper side. Preferably, the chamfer extends towards the brush 4 or towards the center of the clamp 6, particularly all around. In this way, liquid can be channeled from the brush 4 onto the edge of the clamp 6 or the sleeve and into the brush.

[0042] In its assembled state (see below). Fig. 1) The connecting pin 10 of adapter 3 and the internal thread 11 of the clamp 6 of brush 4 are screwed together. The annular end face 14 of the clamp 6 then makes circumferential contact with the annular contact surface 15 of adapter 3. This circumferential contact and the screw connection ensure a secure hold of the brush 6 against adapter 3. At the same time, the circumferential contact creates a seal.

[0043] How Fig. 3 is removable, a passage 12 is formed in the connecting pin 10, which extends through the adapter 3 to an inlet opening 16 in the lower area of ​​the adapter 3 facing the storage container 2.

[0044] How Fig. 2 is removable, in turn a central passage 13 is formed in the clamp 6 of the brush 4, which extends from an adapter-side end of the brush 4 in the longitudinal direction of the clamp 6 to the bristles 5.

[0045] In the assembled state of brush bottle 1 according to Fig. The described design enables the liquid 17 in the reservoir 2 to enter the adapter 3 through the inlet opening 16, provided the reservoir 2 is sufficiently full and the brush bottle 1 is tilted accordingly. It then flows out through the passage 12 of the adapter 3, from where it reaches the bristles 5 of the brush 4, particularly through the passage 13. Alternatively or additionally, if the reservoir 2 is flexible in shape (e.g., made of plastic), the liquid can be forced out of the reservoir 2 by manually squeezing it and into the bristles 5 of the brush 4.

[0046] Accordingly, in the case of the brush bottle 1, both the threaded connection 9 between adapter 3 and reservoir 2 and the threaded connection 10, 11 between brush and adapter 3 are preferably each hollow in order to be part of a passage running through the adapter 3.

[0047] As in Fig. 1 and Fig. As shown in Figure 3, the adapter 3 has a C-shaped handle 7 on its rear side. This facilitates one-handed holding and handling of the assembled brush bottle 1. It should be noted that the brush bottle achieves most of the aforementioned effects even without such a handle. The brush bottle can also be gripped by the reservoir 2 or directly by the adapter 3, which also allows for easy, and especially one-handed, handling.

[0048] The brush bottle described using the exemplary embodiment offers decisive advantages due to the described features.

[0049] Due to the design of the reservoir, adapter and brush as a single structural unit, the brush bottle can be held and operated with one hand, advantageously ensuring that the brush can be supplied with liquid during application.

[0050] By selecting a suitable offset angle between the brush and the reservoir, as well as a suitable diameter in the feed through the adapter, the operator can intuitively achieve appropriate liquid dosing.
